Synthesis of (Ca,Nd)TiO3 powders by complex polymerization, Rietveld refinement and optical properties
(Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy, 2009-12-01) [Artigo]
Neodymium calcium titanate, (Ca0.99Nd0.01)TiO3 powders were synthesized by the complex polymerization method and heat treated at different temperatures for 2 h under air atmosphere. The structural evolution of these powders ...
Intense blue and green photoluminescence emissions at room temperature in barium zirconate powders
(Journal of Alloys and Compounds, 2009-03-05) [Artigo]
Intense blue and green photoluminescence (PL) emissions were observed at room temperature in barium zirconate (BaZrO(3)) powders prepared by chemical method. The powders were analyzed by X-ray diffraction (XRD), X-ray ...
Microstructure, dielectric properties and optical band gap control on the photoluminescence behavior of Ba[Zr0.25Ti0.75]O-3 thin films
(Journal of Sol-Gel Science and Technology, 2009-01-01) [Artigo]
Ba[Zr0.25Ti0.75]O-3 (BZT) thin films were synthesized by the complex polymerization method and heat treated at 400 A degrees C for different times and at 700 A degrees C for 2 h. These thin films were analyzed by X-ray ...
